Why AI can displace work like the trades/construction/nursing quicker than we think.

Aside from the obvious displacement where a large pool of skilled white collar workers (engineers, lawyers, marketing etc), are thrown into the economy to 're-skill' into the fields that are harder to replace & automate (trades, construction, etc), leading to increased competition for entry roles and wages shifting downwards for experienced workers. I think there is something else that isn't getting as much attention.
